bzzzt, wrong

bzzzt, wrong /bzt rong/  [Usenet/Internet] From a Robin
   Williams routine in the movie "Dead Poets Society" spoofing
   radio or TV quiz programs, such as *Truth or Consequences*,
   where an incorrect answer earns one a blast from the buzzer and
   condolences from the interlocutor.  A way of expressing mock-rude
   disagreement, usually immediately following an included quote from
   another poster.  The less abbreviated "*Bzzzzt*, wrong, but thank
   you for playing" is also common; capitalization and emphasis of
   the buzzer sound varies.
